What is the proper maintenance routine for an Audi 80?

I just bought an Audi 80 and want to make sure I take good care of it. What are the recommended maintenance tasks and intervals for this car model?

Perform regular oil changes every 5,000 miles to keep your engine running smoothly. Also, make sure to replace the oil filter at the same time.

Check and replace your air filter every 12,000-15,000 miles to ensure proper air flow and engine performance.

Be sure to inspect your tires regularly for wear and maintain proper tire pressure to improve handling and fuel efficiency. Also, rotate your tires every 6,000 miles for even wear.
